nucleate boiling simulation in CFX
 
Hi All,

I'm trying to simulate nucleate boiling phenomena in generator. Flow is taking place across Tube Bundles. Steam is flowing inside tubes. For this i had taken datas from experimental setup(shell n tube type heat exchanger), Now I wish to do it's simulation. I did simulation for flow across tube bundles, I want to know how to simulate it for boiling phenomenon. if anybody has done this type of simulation in past than please suggest me how to proceed for that.

thanking you,

hi,
I'm trying to simulate nucleate wall boiling by CFX
may I ask you to send me a tutorial about it??!
let me thank you in advance

Create a fluid domain with two components, water and steam, then use the RPI boiling model that is included. Note however, that the model in its current form does only work for high pressures. Subcooled boiling at low pressures does not work.
